hopefully if there are any snakeheads in that pond it will die off when the cold wheather hits.i had owned a few of these fishes in the past but they died becuase they jumped out of the fish tank.the one in the pics on the province look like the Emperor snakehead....these guys are nasty trust me.i used to throw a bunch of feeder in my tank to see what would happen.....the thing ate till it was twice its normal size!they have a very big appetite.all i know is that they dont do well in cold water i was surprised to find out that its in central park i always thought our waters would be too cold for them.
